WebPhotochemical rearrangements Many photoreactions are known to interconvert isomeric compounds. The term “ rearrangement ” is more general than “isomerization” but for the reactions under photochemical rearrangement will not be concerned with a distinction between these terms. WebC−C bonds through a Brook rearrangement can be apowerful synthetic tool. In this chapter, we investigate an intermolecular coupling of aryl acylsilanes and aldehydes through a metal-catalyzed Brook rearrangement under transfer hydrogenation conditions to yield two synthetically useful motifs, specifically oxygenated bicyclic compounds.

WebDec 14, 2024 · If substoichiometric or catalytic amounts are added, the normal Brook rearrangement takes place with the silyl ether being the more stable species. Under excess butyllithium conditions, the retro-Brook rearrangement takes place indicating that under those conditions the alcoholate is the more stable species. [3] WebMar 18, 2024 · We illustrate the applicability of our setup following the photo-Brook rearrangement of (adamant-1-yl-carbonyl)-tris (trimethylsilyl)silane, address photo … In summary, we have identified a novel class of photoaffinity warheads with short irradiation times capable of generating α-siloxy carbene intermediates suitable for photoaffinity labeling applications at long UV wavelengths in both cell lysate and with pure protein. Further studies are underway to better … See more Identifying drivers of on- and off-target phenotypic responses to bioactive small molecules remains a significant challenge in the field of drug discovery, particularly for low-affinity or low … See more The experimental data, including procedures and characterization data, have been uploaded as part of the ESI.† See more We began by synthesizing a probe that contained an alcohol as a modular site of attachment for conjugation to a small molecule of interest and an alkyne handle, which could be used for either pull-down experiments or … See more F.
